Question

The length of a rectangular sign is 3 times its width. If the sign’s perimeter is 32 inches, what is the sign’s area?

Answer 1

Answer:

48 inch²

Step-by-step explanation:

Let the width of rectangle be x.

Length of rectangle = 3x

Perimeter of rectangle = 2(l+b)

Given perimeter = 32 inches

=> 2(3x+x) = 32

=> 4x = 16

=> x = 4

Hence, width of rectangular sign = 4 inches

Length of sign = 3×4 = 12 inches

Area of sign = (12×4) inch² = 48 inch²
